A) Sends sensory information to the cerebellum and the midbrain
B) Transmits information on the body's position to the brain

D) Begins the transmission of nerve stimuli related to sound
B
Feedback:
The semicircular canal transmits information on the body's position to the brain. The vestibule sends sensory information to the cerebellum and midbrain, whereas the transmission of nerve stimuli begins in the cochlea, and the auditor tube equalizes the pressure in the middle ear with the atmospheric pressure. The semicircular canal does not send sensory information to the cerebellum and the midbrain, begin the transmission of nerve stimuli related to sound, or equalize the pressure in the middle ear with atmospheric pressure.
